Radon Testing

You’re wise to check your new home for Radon before you buy. The EPA says all homes can have Radon. This includes new homes as well as older homes. No mitigation systems installed in your neighborhood may simply mean those homes haven’t been tested.

So, what results do you need to make a decision about Radon levels. The answer is simply the average concentration over the testing period. This includes short term tests, as in a Real Estate transaction, or long term tests that might be done to monitor the effectiveness of an installed mitigation system. The EPA has set 4.0 piCul as the action level for a single family home. At or above that level requires a mitigation system to reduce harmful Radon levels.

Independent Home Inspection uses an electret based Radon monitoring system to measure your homes Radon level. Electrets have an initial electrical charge that decays at a known rate in the presence of Radon. I use annually calibrated equipment to measure the electret charge before and after exposure and a computer generates the result on the basis of the measured differences.

Electret systems advantages are many. They require no power source during testing. They continuously respond to Radon exposure rather than sampling (other methods sample hourly or ½ hourly). Results do not require a lab and accurately indicate the Radon average over the testing period. In fact this method of Radon testing has been determined to be the most accurate system available today.

Independent Home Inspection is available to test your homes Radon either with a home inspection or alone. Call or text today for availability and cost: 410-504-3751

Montgomery County Radon Law

Montgomery County Bill 31-15 will take effect on October 1st of this year requiring radon testing for certain residential Real Estate transactions.

In an article published last fall the ‘Bethesda Beat’ discusses some of the ramifications of this bill.

The article erroneously suggests, however, that radon test kits can be had for as little as $15-25 at hardware and lumber stores. Had the authors taken the time to actually read the instructions with these kits, they would have known that an additional $50-75 fee is necessary to submit these kits to a lab by mail.

For a Real Estate transaction the time required to test and mail the kits may not accommodate the settlement schedule. Radon Testing for a Real Estate transaction will require a minimum two day (48 hour) short term test. A professional Radon Testing company, like myself, can provide results the same day that testing concludes.
